Multithreading: An Extensive Study on Linux, OpenSolaris, and Windows

There are many reasons why one may choose a particular operating system to run on their computer: availability of software, technical skills, etc. Among those reasons one may choose the operating system with the best performance, or the one with the lowest cost per transaction. This paper examines three operating systems (Linux, OpenSolaris, and Windows) and their respective capabilities of taking advantage of the multiple cores present in modern processors by executing operations with integers, floating points and math, and I/O in a multithreaded way, achieving parallelism in the execution of those operations, and then tries to reason the measurements from the experiments in the economics of an operating system.

A Different Approach to a Window System: The Modeling and Applications of a Non-Overlapping Window Environment.

The era of Web 2.0 allowed us to implement and use windows inside a web browser, without impact neither on performance nor usability. The possibility of desktop-like experience while using web applications, broads the horizon of programs that can benefit from all the advantages that come with the Internet.

In this paper we are going to explore a different approach to how a dynamic window system can function and behave. Windows squeeze and expand, resembling an accordion. This way, windows give a little space to other windows (when required) , or request a larger area, within the canvas, to allow the user to concentrate his/hers focus, without loosing the sight of what is in the other windows.
